TUFLOW Message 2178: Difference between revisions

|message_desc=Null cell must be specified adjacent to BC cell. If the <font color="blue"><tt>Null Cell Checks </tt></font><font color="red"><tt>== </tt></font><font color="black"><tt>ON</tt></font> command is used in the .tcf TUFLOW checks that null cells occur on one side of an external boundary. A TUFLOW simulation prior to Build 2001-08-AE will not proceed unless a null cell occurs on one side of an external boundary cell (this was used to indicate the inactive side of the boundary line). Setting this to OFF (the default) allows ESTRY models to be inserted through the 2D domain with no need to specify null cells (eg. a 1D creek flowing through a 2D floodplain). It also allows land cells, instead of null cells, to be specified against a boundary on the inactive side.

|suggestions=This command may prevent linked 1D/2D models from running. For external boundaries null cells should occur on one side of boundary.
